Pulsus alternans developed during intra-abdominal procedures and general anesthesia in a patient with dilative cardiomyopathy, resolving after nitrous oxide discontinuation.
Case Report (n=1)
No
Pulsus alternans can be transiently induced by intra-abdominal procedures and general anesthesia (particularly nitrous oxide) in patients with underlying dilative cardiomyopathy, even in the absence of overt heart failure.
Alerts anesthesiologists to monitor pulsus alternans in cardiomyopathy patients under nitrous oxide; leaves open causality in larger cohorts.

Ozaki et al. (1994) conducted a case report in Dilative cardiomyopathy and end-stage renal disease on CAPD (n=1). General anesthesia and intra-abdominal procedures was evaluated on Development and resolution of pulsus alternans. Pulsus alternans developed during intra-abdominal procedures and general anesthesia in a patient with dilative cardiomyopathy, resolving after nitrous oxide discontinuation.
